双站机载测向定位最优布站分析

本文主要针对双站测向定位系统观测平台的几何分布对定位精度有直接的影响这一特点,分析了双机载平台协同对目标测向定位时,交会角与俯仰角对定位精度的影响。通过对二维几何精度因子的分析,得出了目标与平台呈等腰三角形分布有利于提高定位精度的结论。并以此结论为前提,对三维几何精度因子进行分析。通过仿真实验得出了可以进行有效定位的交会角和俯仰角范围。

Optimal Embattling Analysis on Double Airborne Platform Bearing-only Location

In the view of characteristic of double platforms bearing-only location system that the geometric distribution of observation has a direct impact on the positioning accuracy, this paper analysis the influence of cut angle and pitching angle on the positioning accuracy. Through the analysis of two-dimensional geometric dilution of precision, draw the conclusion that it is more beneficial to locate when the distribution between target and two platforms is isosceles triangle. On the premise of this conclusion, the paper studied on the three-dimensional geometric dilution of precision. Finally, the paper obtains the range of cut angle and pitching angle when can effectively locate by simulation experiment.
